Abstract:Aggregates used for seal coats should consist essentially of a single-size stone. When
determining binder application rates in the field, achieving an embedment depth of the stone into
the asphalt binder of about 40 to 50 percent is the goal. If all of the aggregate particles are about
the same size, embedment depth will be about the same for each particle contributing to
successful seal coat performance.
